Abstract Background Mirikizumab (miri), an anti-IL-23p19 antibody, is approved for the treatment of ulcerative colitis and under development for Crohn’s disease (CD). We investigated how miri impacted fatigue, bowel urgency, and health-related quality of life (HRQoL) through 52 weeks in patients with moderately to severely active CD in the Phase 3 VIVID-1 study. Methods In the treat-through VIVID-1 (NCT03926130) study, patients (N=1065) with moderately to severely active CD and a Simple Endoscopic Score for CD (SES-CD) score ≥7 (or ≥4 for patients with isolated ileal disease) and failure to biologic and/or conventional therapy were randomized in a 6:3:2 ratio to receive miri (N=579) (a single 900mg intravenous (IV) dose at W0, W4, and W8 followed by a subcutaneous (SC) dose of 300 mg at W12 and then every 4 weeks), ustekinumab (N=287) (6mg/kg IV at W0 and SC dose of 90mg at W8 and then every 8 weeks), or PBO (N=199). At W12 PBO responders continued PBO to W52; PBO-non-responders received the same blinded miri regimen as described above. This analysis focuses on results in patients randomized to either miri or PBO. The change from baseline for Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Urgency Numeric Rating Scale (UNRS), and Inflammatory Bowel Disease Questionnaire (IBDQ) total and domain scores (bowel symptoms, systemic symptoms, emotional function, social function) were analyzed through W52. IBDQ response (≥16-point improvement from baseline) and remission (total score ≥ 170) rates were also analyzed at W12 and W52. For binary variables, adjusted risk differences were compared between miri and PBO using the Cochran-Mantel-Haenszel (CMH) test. For continuous variables, least squares mean changes from baseline were compared between treatment groups using ANCOVA. Results Significant improvement in mean change from baseline to W12 and W52 were observed with miri for FACIT-F, UNRS, and IBDQ total and domain scores (all p
